How Defrost approaches the work
Defrost starts with your website and the audience you want to reach. It finds people, researches their companies, writes personal emails, sends and follows up. Reply outcomes help shape future emails as evidence builds. When someone replies, you pick up the conversation in one inbox.
The intended experience is one ongoing system. You can adjust the business information, audience and sending settings, pause outreach, or choose whether first emails need approval. Public access is currently through the waitlist.
